To all 'whom t 'may concern.'-

Be it known that I JOHN J. DU Bois, a citizen of the United troit, in the county of Wayne and Michigan, haveinvented new and use provements in Eraser-Reels, of which .the following is a specification. l

The present invention aims in providing a novel construction of eraser attachment or typewriting machines designed for attachment to the typewriter in such a manner whereby the operator may conveniently make erasures in an'expeditious manner and pre`= vent any unnecessary loss of time.

The primary object of the invention resides in theproduction of a device of the above stated character, .which is simple'in construction, durable and ecient in use, and one which may be quickl and easily repaired, and manufacture and sold at a minimum cost.

A still further object of the invention is the provision of a frame of novel constructien 'adapted for supporting therein the reel on which is automatically wound the flexible tate of Y eraser connector.

I set forth, illustrated in the' A still further object of the invention resides in the provision of means whereby the reel is operatively connected or associated with the spindle.

With the above the invention consists in the novel features details of construction and combination ci parts which willhereinafter be more fully accompanying drawing and pointed out in the appended claims.- Y

The opening 21' intersects Patente Apr. S, 19in.

drical hollow casing, preferably constructed of aluminum, metal or; the like material, denoted by the character 6 provided with opposite open ends 7. Encircling the casin at formed a beading 8 adapted to engage in the ridge 9 of a cap 10. Each of the caps 10, like the casing, Ais preferably constructed of aluminum or the like material, and is stam ed out to provide pairs of diametrically is- Y posed tongues 11, which2 upon the assembling of the caps to the casing, will rejectinteriorly ofthe casingand at su stantially right angles to the cover, fthe, purpose of which will be hereinafter more fu ly set forth as the description of the invention is proceeded with. The removable engagement oi the caps with they open ends of the casing facilitates the insertion therein of a resilient substantially Ueshaped frame l2, comprising l aced limbs le. Each of the limbs is termina l bent in confronting relation one to the ot er to provide guides 15. Upon the assembling of the frame within the casing, the tongues ll or one cap.

l0 are irst bent around one of the limbs at points adjacent the upper and base portions thereof, the cap thence is shoved onto the casing and the tongues 11 of the other of said caps are .likewise secured in embracin relation to the other of said limbs, establis ing a detachable and rigid connection of the frame within said casing. trated inthe detail view of the vtrame, each of the limbs 14 of the frame 12 is bent at an intermediate point inwardly in line with the connecting-portion 13, to provide on the exbearing or notch 16. ln order to Simp the construction of a device o'this character and to reduce the cost ci manufacture to a minimum, l em loy a flexible spindle 17, here illustrated of su stantially looped formation,4 disposed lengthwise with respect to the frame an casing', with thecrown ends 18 thereof frictionally engaging in the bearings or notches 16 of the frame. Journaled on the spindle ,17. is a reel 19 of sool formation, and keyed or otherwise suita ly secured, to 'the through a transverse openin 210i the reel.

die longitudinal' bore 22 or the reel. Wound u on the periph-s ery et the drum 19 is aiexib e connector ad provided on its vfree end with a suitable iastener, denoted by the character V2e adapted to 6.0 a point adjacent the `open end-7 thereo 1s v As clearly illus me iiexible spindle by the insertion of apin 20 ne l engage in the eraser 25 and establish a connection of the eraser with the attachment, to permit the connector to be automatically rewound on the drum when the use of the eraser is no longer desired. Suitably secured to one of the caps l0 is an attaching member 26, here shown 1n the form of a clip, ada ted to be fastened tc the frame A of the mac ine through the employment of a thumb screw 27.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of construction and the method of operation will be readily apparent to those skilled in the art to which the inven- 'tion relates, and while I have described the principles of operation of the invention, together withl the device which I now consider to. be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and -that such changes may be made when desired as are within the serge of the appended claims'.

aving thus described the what is claimed as new, is

1. An eraser attachment for typewriting machines comprising a casing having open ends, caps for closingthe open ends of the casing, a ,frame mounted in said casing,

invention,

- means carried by the caps and co-acting with the frame for preventing any loose movement of the latter with'respect to said casing, a spindle mounted on said frame, areel keyed-to said spindle, and means for connecting an eraser with said reel.

2. An eraser attachment for machines, comprising a casing having open ends, caps for closing the open ends of the casing, a frame having notched limbs mounted in said casing, means carried by the cap and coacting with the notched limbs of the frame for preventing any loose movement of the latter with respect tosaid casing, a flexible spindle mounted in the notched limbs of the frame, a reel keyed to said spindle, and means for connecting al1 eraser with said reel.

3. An eraser attachment for typewriting machines, embodying a casing provided with opposite open ends, means for closing the open ends of said casing, a reel mounted in said casing, and diametrically disposed means formed integral with the closing means and coperating with the reel for preventing any loose movement of the latter with respect to said casing. A

4. An eraser attachment for typewriting machines, embodying a casing having open typewriting ends, caps for closing the open ends of said casing, means carried by said cap and having engagement with the limb portions of the frame for detachably connecting the latter in said casing, a spindle mounted in the limbs of said frame, a reel keyed to said spindle, and means carried by the reel for connecting therewith an eraser.

In testimony whereof I aiiX my signature.
